ADJUSTABLE LAMP SHADE Filed Feb. 17," 1930 INVENTOR.

Patented Apr. 14, 1931 UNITED STATES HARRY MITCHELL`XOENIG, OF MILWAUKEE, WISCONSIN" ADJUSTABLE-LAMP SHADE Application led February 17, 1930. Serial No. 4:29AM.`

This invention relates to improvements in adjustable lamp shades. f

In rooms where the sick are being cared for, and more especially in hospitals, itis oftentimes desirable to have some light burning in the patients room. so that the nurse may be able to see sufficiently well to perform her duties. The use of a light equipped with the ordinary type of shade, however, is d'isof F'. 1, the 'dotted lines indicating the 10 turbing to the patient, as it casts a glare out in all directions and usually in the patients i e es. v

yIt is, therefore, one of the objects of this invention to provide an improved shade for lamps, which is so constructed as to permit the light to be cast out only in the direction or directions desired and'only in the amount desired. By the imprdved device, it is there fore possible for .a nurse to obtain light of full stren h in one direction to permit the reading o a thermometer or the makingof notes without causingdisturba-nce to the pasimple in construction, inexpensive to manu-- facture, and well adapted for the purpose described.

With the above and other objects in view, the invention consists of the improved adjustable lamp shade, and all its parts and combinations, as set forth in the claims, and ,all equivalents thereof.

In the accompanying drawing, illustrating one complete embodiment of the preferred form of the invention, in which the same reference numerals designate the same parts in all of the views:

Fig. 1 is a side view of an electric light fixture showing a vertical section of theimproved shade in connection therewith, the

dotted lines indicating the manner of withdrawing the bottom closure;

Fig. 2 is a fragmentary view ofa light fixture showing a side view of the shade in connection therewith, the adjustable shutter being shown in fully open position;

Fig. 3 is a similar view showing the adjustable shutter in fully closed position; and

Fig. 4 is a sectional View taken on line manner o withdrawing the bottom closure.

Referring to the drawing, the numeral 8 designates an electric light fixture, and the numeral 9 designates an electric lamp carried thereby. The fixture is 'provided with the usual annular collar 10, carrying set screws l1 to facilitate 'the connection of a shade thereto.

The improved shade comprises a Ybody 12 of box-like formation, which is constructed of opaque or translucent materialQsuch as metal. The upper portion of the shade is provided with an opening 13, through which the electric lamp 9 is adapted to extend. Surrounding the opening is an upwardly extendin g collar 14, which is adapted to tit within the fixture collar 10 and to be engaged by the set screws 11 to hold the shade in position.

The lower ed e of three sides of the shade is provided wit a pair of spaced apart in wardly extending .flanges 15, which define grooves therebetween, the said grooves being open at one side of the shade to receive a slide or bottom closure member 16. The outer end of the closure member is upwardly bent as at 17, and saidupwardly bent portion is provided with a knob 18.

Each side of the shade, as well as the bottomclosure member 16, is provided with one or more perforations 19.\ The said perforations are shown as round, but may, however, be of any desired shape or grouping, and may be of any desired size. A shutter member 20, which is shown in the form of a disk, is also provided adjacent each set of perforations. Each shutter has a pin 21 extending outwardly therefrom through a bore in the shade, the outer end of the pin being provided with a knob-22- Each shutter is further provided with perforations 23, which are adapted to be brought into o rkout of y registration with the perforations 19 of the shade when the shutter is rotated by turning the knob 22. 5 n the use of the device, when all of the shutters are closed, as in Fig. 3, no light will be thrown out into the room. If, however, it is desired to have light cast downwardly, the knob 22 of the shutter on the bottom clorations 23 of said shutter into either partial or complete registration withthe perfora`` tions 19, according td-.the amount of light desired. If itis desired to have light thrown from one side of the shade only, the shutter on the selected side only is turned to give the requisite amount of light, asfshown in Fig. 2. Thus, the shade may be readily adjusted to throw light in a desired amount fromone or more sides or from one or more sides andk the bottom. 4

When an unusual amount of light is required, the bottom slide or closure member 16 may be partially or 'completely withdrawn 25 in the manner indicated in Figs.Y 1 and 4. By

moving the closure member only a short disly tance, a narrow st ripVV oflig'ht willbe thrown downwardly, and by withdrawing the shutter completely the amount of light will be 3o considerably increased.

Although only one form. of the invention has been shown and described, it is not desired to be limited to the exact showing, as the broad concept of the invention includes all changes 'andfmodifications as may come within the scope of the claims. Y What I claim is y y 1. A lamp shade comprising a hollow body portion of opaque material having opposite alined end openin for accommodating a lamp and for permltting its insertion respectivel and having an additional opening at' a si e thereof through which lightmay be emitted, and shutter means adj acent said last mentioned opening, said shutter being adjustable to vary the amount of exposure of said opening.

2. A lamp shade comprising a hollow body portion of opaque material having an opentional openings on a. lurality' o? sides through which light maylbe emitted, and independent shutter means for said openings oneach side to permit selective control of the light -thrown out by the lamp within.

3. A lamp shade comprising a hollow body portion of opaque material normally closed at the bottom, said body portion having an openin for receiving a lamp and having additiona openings on a plurality of sides and on the bottom through which light may be emitted, and independent shutter means for said openings on each side and on the bottom to permit selective control of the light 5 thrown vout by the lamp within.
